LOS ANGELES — Just call him Sam Dagger.

Sam Dekker hit five of Wisconsin’s 10 3-pointers in the second half on his way to a second straight career high of 27 points, Frank Kaminsky added 29 points and the top-seeded Badgers beat No. 2 seed Arizona 85-78 on Saturday to reach consecutive Final Fours for the first time in school history.

The Wildcats twice got within five points in the last 2½ minutes, but both times Dekker connected on arcing 3-pointers, narrowly beating the shot clock on the first one.

“Sam Dekker pretty much just crushed our dreams with that shot,” Arizona guard T.J. McConnell said.

Dekker confirmed the Badgers are more than just “Frank the Tank.”

The junior followed up his career-high 23 points and 10 rebounds in a regional semifinal win over North Carolina with timely shooting that bailed out the Badgers.

“Incredible game,” tweeted Packers quarterback Aaron Rodgers from his seat behind the Badgers’ bench, calling Dekker “cold blooded.”

Wisconsin (35-3) denied the Wildcats (34-4) a Final Four berth for the second straight year, having beaten them by a point in overtime in Anaheim a year ago, when their seeds were reversed.

“That loss left a sour taste in our mouth, so we wanted to get back,” Dekker said of last season’s one-point loss to Kentucky in the national semifinals. “As a team we set some goals of what we wanted to do, and now we’re two games away from our last goal.”

The Badgers and 67-year-old coach Bo Ryan head to Indianapolis next week hoping for another shot at undefeated and top-seeded Kentucky.

“I’m so proud of these guys to be able to say that they’ve answered the bell in the second half in almost every game we’ve played here in the last seven to 10 games,” Ryan said. “They’re a tough bunch, and I hope they don’t change.”

Rondae Hollis-Jefferson and Brandon Ashley scored 17 points each for the Wildcats, who once again failed to deliver a first-time Final Four appearance for coach Sean Miller.

McConnell added 14 points in his college finale, and Kaleb Tarczewski and Gabe York had 11 each.

“It was tough to be playing hard on defense and trying to get a stop to win the game and he made those shots,” Hollis-Jefferson said of Dekker. “It was tough to watch them go in, but in basketball you have those days.”

Miller compared the Badgers’ offensive execution and ability to make shots to a video game.

“Sam Dekker and Frank Kaminsky, they’re really good,” Miller said. “No team has done what they did to us in the second half. They made shots, and if they play like that next weekend, they have a chance to win it all.”

The Badgers hit 10 of 12 3-point attempts in the second half — connecting on a season-high 67 percent overall — and outscored the Wildcats 30-3 from long range. Dekker had five 3-pointers and was named most outstanding player of the West Regional.

“This tournament, he’s really shown his full arsenal offensively and defensively,” teammate Josh Gasser said. “When he’s confident like that making plays, being aggressive, this is the stuff that happens.”

Arizona closed within two points early in the second half, only to watch Dekker casually fling up a rainbow 3. The Wildcats got within one a minute later and Dekker let loose with another high-arcing 3, sending Badger fans into delirium.

“Eventually when that ball gets out, everybody on the court can shoot it, and they get you with an open 3 that breaks your back,” Miller said. “They had two 3s at the half. Think about that.”

Arizona pressured full court in the last 4 minutes, making for some perilous possessions by the Badgers as they darted and passed trying to safely get the ball down court. A long inbounds pass by Wisconsin was nearly intercepted before Gasser grabbed it, got fouled and made both free throws to keep the Badgers ahead by 10 points.

“Emptied the bucket, and it was a big one,” Miller said of his defensive schemes. “We’ve tried everything.”
